6. In this example, we want to read and write only to the SmartServer’s digital relay outputs;
therefore, we need to modify the List function so that it returns the subject data points. To do this,
change the xSelect statement from:
//Item[@xsi:type="Dp_Cfg"]
to the following:
//Item[@xsi:type="Dp_Cfg"][contains(UCPTaliasName,"nviClaValue")]
This means that the List function will return only those data points that have “nviClaValue” in
their alias names. The xSelect statements you will use will depend on the subject data points, as
you can filter for desired items using the appropriate xsi type and predicates such as contains and
starts-with.
